Hey dudes, I've been noticing a few spots on some of my plants lower fanleaves. Take a look and tell me what you think, I'm about 6 days into flowering.

Do you have a pic of the whole plant? Are you feeding enough Nitrogen, you still need to feed veg nutes for the first few weeks of flower to keep those leaves green...

I run FNB veg and flower. I also run maxibloom from veg thur flower and have no issues with my leaf yellowing. By the looks of some of those leafs curling you have enough N adding more isnt going to solve your problem. Its really hard for anyone to give you an accurate answer with so little info. A pic or two of the whole plant in natural light would be a big help. What is your base ppm of your water? What are you growing in soil/coco/promix.... Could be a little cal issue, from what I see, looks to be the same thing I get when I need to bump my cal/mg up a bit. If I have been under feed cal/mg thur veg it always shows the first two weeks of flower during the stretch phase.
